The monitoring of natural and artificial gamma fields has become an indispensable auxiliary tool not only in the search for minerals or geophysical research but also as a standalone method for assessing environmental conditions during accidents, locating highly radioactive sources, and implementing anti- terrorist measures. Nowadays, the most actively developing method of monitoring gamma fields is the remote method, primarily involving the use of remotely piloted vehicles. Most problems of gamma field monitoring can be solved more effectively by incorporating appropriate mathematical support. In particular, accurately estimating the intensity of gamma radiation of contami- nated soils requires proper consideration of the processes affecting the formation of gamma quanta flow, including attenuation processes. Using the exponential law of gamma ray attenuation in a medium and their geometric divergence, we investigate the problem of gamma field intensity in a layered soil massif. In our research, we derived an analytical expression for describing the field intensity of a two-layer soil depending on the density, thicknesses, and mass attenuation coefficients of the layers, as well as the height of the detector above the soil surface. We identified unique characteristics in the behavior of the field intensity function for different layer configurations and at considerable heights above the soil surface. The algorithm for calculating the intensity of the gamma field is generalized for scenarios involving a finite number of layers. The results obtained could be valuable for developing solutions to inverse problems that arise during remote detection of gamma fields in contaminated areas using, for example, unmanned aerial vehicles.
